Display multiple basemap layers

Learn how to add multiple basemap layers from different services to your map.

This tutorial shows how to display two basemap layers from different services in your application. You will use the World Imagery map tile service satellite imagery basemap to provide the underlying visual and geographic context for the map. To provide additional context, you will use the arcgis/imagery/labels style from the static basemap tiles service to display place labels for the world. The combination of the two layers will result in a basemap that provides additional context for the mapping application.

Prerequisites

Steps

Get the starter app

Select a type of authentication below and follow the steps to create a new application.

Set up authentication

Create developer credentials in your portal for the type of authentication you selected.

Set developer credentials

Use the API key or OAuth developer credentials so your application can access location services.

Update the map's viewpoint

1. Change the map's center to [-91.2996, 37.1174] and zoom level to 4. This will focus the map on the United States of America.

Add basemap layer 1

Create a tile source and tile layer to access and display basemap layer from the World Imagery map tile service.

1. Define a tileSource to load raster tiles from the World Imagery map tile service.

2. Add the data attribution for the map tile layer source.

   • Go to the World Imagery item.
   • Scroll down to the Credits (Attribution) section and copy its value.
   • Create an attribution property and paste the attribution value from the item.

Add basemap layer 2

In this step, you add another basemap layer from the static basemap tiles service to provide place labels.

1. Replace basemapEnum to arcgis/imagery/labels and baseUrl to the static basemap tiles service endpoint.
